Thermal condiut is terrible. You're doing less damage than normal lasers unless you're cooking yourself. Pretty much the worst mod you can put on them.
But the double damage! Have you actualy tryed them out?
You can cook for a while before you get any serious problems. You only need to last one fight.
I tend to run on the basis that every one has solid resistamce across the bord so it comes down to raw dps rather than damage type. So lasers are just hit scan cap hungry heat monster mulit cannons essentially.
I got to try out my idea of using close range thermal conduit beams and the damage out put is quite amazing! But sadly on a viper ots not enough to bridge the gap quickenough to kill a player before your guns melt off. So.. there is that lol
The whole idea came from my melty conda. All efficient thermal conduit plasma! Pop a scb and pulle the trigger and you waft out a massive sunlike ball of super heated death! I think its about 800 damage per volly 60% of wich ish absulute. And you only need to be overheating for 10 seconds at moste. A wepons focused distributor alowws for a quick 2 shot volly so thats 1600 over 3 seconds and another shortly after so its possable to burst down shields on a pvp conda if you catch it buy surpirse especially with 2 small feedback rails. I love melty but its a risky build and expensive to fix and only works against large slow ships lol
